Posted: Mon Jul 16, 2007 9:28 Post subject: VPN, multiple satellite offices. Which firmware/setup?
I have 2 satellite offices and 1 main office. Let's assume that there are 2 computers in each satellite office that need to connect to the main office.
I think there are 2 options:
1. Use site-to-site bridging, as explained in this tutorial.
2. Setup VPN on the main office router and install OpenVPN on the 4 client computers (2 computers in 2 satellite offices).
Is there any advantage to choosing one option over the other?
My main question concerns site-to-site bridging. Is this even possible when connecting multiple offices to the main office? If so, what version of DD-WRT do I need? According to the tutorial I mentioned above,
Quote:
Use v23 sp3 or greater if you want to connect multiple clients to one server simultaneously. Single client to server works fine with sp2.
On the 3 Linksys WRT54GL v1.1 routers, I currently have the latest stable release of DD-WRT v23 SP2 installed. To allow multiple computers in multiple offices to connect to the main office, do I have to upgrade to the beta version v23 SP3?
And here's an easy question, to clarify my terminology and understanding. In the scenario that I presented and the quote above, what is a "client"? Do I have 2 clients (the 2 routers in the satellite offices) or do I have 4 clients (the 4 computers in the 2 satellite offices)?
No responses. Maybe I asked too many questions at once, so let me ask the most important question.
If I have 1 satellite office with 2 computers that I want to connect to a central office via VPN, both offices equipped with a Linksys WRT54GL, do I need v23 or v24 installed on the routers?
I don't know if you have to change to SP3, but I have it working with v23SP3.
Under OpenVPN point of view, you have just 2 clients (the 2 other routers
that connect to the main router), so you need just 2 certificates.
Computers that are behind any router, will see each other.
I believe there are people running this in v24, but have no idea what versions to avoid.
